Can't change device title - error: [Errno 111] Connection refused

When I added a bunch of devices it set the Device Title to the DNS name. I'm going through and changing the Device Title in a number of the devices and about half went through no problem but the other half won't let me change them. An "unable to connect to server" pop up flashes for a split second and then goes away. It seems like it went through but then the name is not changed. In the event.log I get the following error:

Sounds like a daemon or service died. Can you try running this script: https://github.com/dpetzel/zenoss_analyzer

Hi David. I found reference to this utility in another post and ran it. Here's what I got at first:

I'm with Shane. These two lines are concerning
ERROR - Daemon: zenhub not running
OK - mysql service is running
ERROR - rabbitmq-server service is not running

I'm guesing zenhub is jacked, because rabbit is unhappy. At the very least I think the script as told us you need to focus on troubleshooting the rabbitmq issues first.
